It's going to come down to your tune. If it's rich they will not last as long. My car idles and cruises pretty lean and I'm sure I could do it even though I never have.

You hit the nail on the head Speedy. My car drove everywhere on 8's. It was tuned on 8's and I sprayed on the 9's and 10's I ran. Im a hardcore street car guy so I could give 2 ***** about idle quality, I just want to make it to the track or wherever Im going without fouling plugs. So I tuned the car myself with the cold plugs in and it was great.

I run TR6's on the motor and swap them out for non-projected tip 8s at the track. no reason to run an 8 just to get to and from the track.
NGK B8EFS stock # 1049
Autolite - AR474
Both non-projected tip heat range 8 plugs...If you need part numbers 9's 10's or anything else just let me know

I tested out the non projected 8s they worked great loaded the car on the trailer and made serveral passes and loaded back up with no issues just tunning the car for the DP. When im ready to set some new personal best I will be switching them out before the run. thanks
